A deep-V halter dress shows numerous smaller vertical silver-coloured reflections. The upper side sections lead towards the neck while the front centre remains clearly open. A high side leg opening has a ruffled shiny-looking border. Pale shoes with several narrow straps are visible below. Both arms rest more loosely at the sides. The photograph is less finely resolved than some references, but still permits comparison of the deep V, bare shoulders and distinct slit edging. It does not identify a particular embellishment or fibre from those reflective details.
If you like the open centre, compare it with a higher front edge on your own dress. Test an intended necklace separately and choose whether you want more jewellery inside the V. Decide about the ruffled edge afterwards: you might like the neckline but prefer a quieter skirt finish. Find that combination on an actually available model. Test the slit walking and sitting in your intended shoes. The visible straps provide a shape idea rather than a required heel height or established length adjustment for your own garment.
